Abstract:
Decision making requires multiple perspectives
of different people as one single decision maker may have not
enough knowledge to well solve a problem alone. This is
particularly true when the decision environment becomes more
complex. More organizational decisions are made now in
groups than ever before. Group decision making is thus a
process of arriving at a judgment or a solution for a decision
problem based on the input and feedback of multiple
individuals. At the same time in practice, multi-criteria
problems at tactical and strategic levels often involve fuzziness
in their criteria and decision makers’ judgments. Relevant
alternatives are evaluated according to a number of criteria.
Fuzzy logic based multi-criteria group decision support is
justified to analysis long-term options for Belgian energy policy
in this paper.
